Yes, lowering the ocean's carbonate concentration can still affect organisms that don't form CaCO3 by disrupting their ability to regulate their internal pH levels. These organisms rely on a stable carbonate system in the ocean to maintain homeostasis and carry out essential biological processes. A decrease in carbonate concentration can lead to ocean acidification, affecting their survival and reproductive success.
When a marine water protozoan is placed in fresh water, it experiences osmotic stress due to the difference in solute concentration. Freshwater has a lower concentration of solutes compared to the protozoan's internal environment, leading to water entering the cell through osmosis. This can cause the protozoan to swell and potentially burst, as they are not adapted to cope with such a drastic change in osmotic pressure. To survive, they would need to actively regulate their internal conditions or find a way to return to a saltier environment.
A cell would need to perform endocytosis to maintain its internal environment when it needs to take in nutrients, remove waste products, or regulate the levels of certain molecules within the cell.
the shark would win unless its a large jelly species.
It would depend on the species of shark. If it was a baby shark that only ate small crabs and shrimps, the eel. If it was a great white shark then the shark.
Whale would eat the shark not grind it shark would eat insides shark wins whale loses
tiger shark
Reptiles are cold blooded and require the atmospheric heat to regulate their internal body temperature. If the outside temperature were to decrease by 20 c the internal temperature of the reptile would decrease 20C.
a tiger would win
I would say bull shark because they're way swifter and probably have a stronger bite.
A shark
Mostly the Tiger shark would win. Most species of hammer heads are smaller than the tiger shark and hence would lose.
